The safety of process automation

Automatica, 1993
The effect of automation on process safety is not clear. On the one hand, automation is blamed for posing risk and for increasing the chance of human error in situations involving disturbances; on the other hand, it is admitted that automation enables sophisticated process control and handling of disturbance situations without human interference.

Safety Process Patterns: Demystifying Safety Standards

2012 IEEE International Conference on Software Science, Technology and Engineering, 2012
Development of safety critical embedded systems is regulated by legislation and related standards. However, at least for beginners in the field, the standards are relatively hard to understand hindering their practical applicability. In this paper, we propose using process patterns to document the requirements for different lifecycle phases set in the ...

Safety assurance in process control

IEEE Software, 1994
Programmable logic controllers are popular in process-control applications, but the software can be very complex. To make it easier to verify the safety of PLC software, we have created a rigorous process that uses formal specifications of function blocks, which are typically used in safety-critical control and automation applications.

Process safety leadership: Becoming street smart on process safety

Process Safety Progress, 2013
It is well known in business improvement circles that good management does not necessarily equal good leadership. This applies to process safety management (PSM) as well. Effectively leading the translation of PSM to action for all whom it affects takes several concurrent actions beyond what is written in PSM regulations.

Designing safety into products and processes

1994
Effective HACCP Systems will manage and control food safety issues on an ongoing basis but what they cannot do is make a fundamentally unsafe product safe. It is essential that food safety is designed into a product at the development stage and this should be the responsibility of Product Development and the HACCP Team working together.

A Safety-Critical Assessment Process

2014
Use of systems containing software is increasing rapidly in the safety-critical domain. It creates pressure to develop more rigorous process assessment methods for assessing systems and software development. The assessment process aims to ensure credibility and repeatability of assessment results.

Managing process safety information based on process safety management requirements

Process Safety Progress, 2013
Many accidents in process industries have occurred because of employees did not recognize the hazards and risk associated with the activities they were undertaking such as when operating, changing, or maintaining processes, plants, and equipment. Recognizing these hazards and risk requires a company to develop and maintain a corporate memory through an

Safety as a Process Quality Characteristic

2013
Software is increasingly been used to provide system functionality that is related to safety. From systems point-of-view safety is often considered to be a probabilistic property and development process has less significance. For software this approach is not necessarily valid.

Process safety culture in the CCPS risk based process safety model

Process Safety Progress, 2007
AbstractThe American Institute of Chemical Engineers (AIChE) Center for Chemical Process Safety (CCPS) has developed a guideline describing a new risk‐based approach that an organization can use in defining and implementing a process safety management system specific to its unique needs.
